901HS High Sensitivity ESD Event Detector - 1

Electrostatic discharge (ESD) events are important indicators of excessive charge accumulation in environments where they may be detrimental to manufacturing processes in the semiconductor or LCD industries. • Five LED indicators or an external display indicate the detection of ESD events • An audible alert indicates ESD events • Automatic or manual reset control • AC or Battery operated, compact, and portable Model 901HS High Sensitivity ESD Event Detector • Sensitive to ESD voltage levels as low as 10 V at 50 mm • Suitable for CDM (Charge Device Model) • Two antennas provide high sensitivity in detecting electrostatic discharge events Trek’s Model 901HS is a diagnostic tool used to identify incidents or verify suspected areas of ESD activity. Electromagnetic waves, generated by electrostatic discharge, transmit differently in different environments. In order to accommodate these differences, the Model 901HS includes two antennas - one active and one passive - that can be used for detection purposes. The determination of which antenna to use will typically be based on the environment in which it’s being deployed and the level of detection that is required. The active antenna may be connected directly to the Model 901HS or with an extension cable that lengthens the antenna to 1.5 meters. It provides high flexibility in positioning the antenna to achieve the best possible reception. The active antenna can detect ESD events as small as 10 V, at a distance of 50 mm. A passive, monopole antenna is also provided. This antenna has a detection capability that identifies ESD events as small as 50 V, at a distance of 90 mm and is generally used when less sensitive detection is required. When an ESD event is detected, the Model 901 signals the operator by playing an audible notification tone and by displaying the detected event level visually via its five LED lights. Since measurement results will vary due to the distance from the signal source and whether there are physical obstacles present in the environment, the LED display indicates a relative signal strength rather than an actual signal strength. A stereo connector on the Model 901 enables connection to an optional external display device to display the measurement results.
